San Francisco and New York retain the top two positions in the Savills Tech Cities Index 2025, with the Californian city benefiting from the rapid advancement of artificial intelligence (AI), while London climbs from fourth to third place.

According to the international consultancy, North American cities make up half of the Tech Cities top 10 and 40% of the top 30, confirming the United States’ dominant position in global technology.

After several years of adjustment, the city is seeing above-average office demand and a 10.5% increase in prime rents over the past two years, with the technology sector accounting for 70% of the largest new leasing deals.

New York ranks second, with a diversified tech base supported by skilled talent and its role as a cultural and lifestyle hub.

London propels European tech

In Europe, London rises to third place, becoming the Tech City with the highest number of top universities, which fuels innovation and the development of highly qualified professionals. The city also stands out for its specialisation in Fintech, CleanTech, DeepTech and AI.

After London, the index places Paris in 15th, Berlin in 19th, Stockholm in 22nd, Amsterdam in 24th and Munich in 25th. The Dutch capital climbs five places, with funding in DeepTech and FinTech more than doubling since 2023, while Barcelona (39th) and Madrid (45th) move up more than 10 positions, in line with the strengthening of the Spanish economy and the growth of highly qualified professionals.

Lisbon, meanwhile, is still not part of the top 100, although it appears in other Savills rankings as a rising destination for international talent and high-skilled remote work.

East strengthens its presence on the global tech map

In the Middle East, Dubai jumps 20 places to 43rd, boosted by national AI strategies, strong population and business growth, and high lifestyle attractiveness.

In the Asia-Pacific region, Singapore enters the top 10, climbing three places to 9th, supported by political and regulatory stability, high-quality infrastructure and a robust business environment, while Seoul rises four positions to take 10th place.

Rising urban wealth, migration flows and stronger policies supporting AI, quantum computing and biotechnology underpin this performance, with both cities recording low office availability and limited supply, which keeps rents high.

In China, six cities rank in the top 30, with Shanghai in 5th and Beijing in 6th place, driven by the size of the domestic market and the dynamism of local tech companies.

Paul Tostevin, Head of World Research at Savills, states that the tech industry is undergoing a profound transformation driven by AI, but human capital remains the sector’s main asset. He adds: “The cities that perform best in our index combine dynamic urban living with a strong cultural and lifestyle offering. Major hubs, with diverse amenities, broad business bases and deep talent pools, continue to dominate the top 10. For investors, owners and developers, a Tech City translates into increased demand for real estate—whether for more office space for tech companies or housing that meets the needs of a highly skilled, mobile workforce.”

As part of the Impacts thought-leadership programme, the index, created in 2015, analyses the business and technology environment, urban dynamics and wellbeing, talent, and the weight of several tech subsectors across 100 cities worldwide.
